Answer: [tex]200\Omega[/tex]

Explanation:

Given

The battery used is 6V in magnitude

The current flow is 90 mA

If the resistance of A is [tex]100\Omega[/tex]

Net resistance of the circuit is

[tex]R_{net}=\dfrac{V}{I}\\\\\Rightarrow R_{net}=\dfrac{6}{90\times 10^{-3}}\\\\\Rightarrow R_{net}=\dfrac{200}{3}\Omega[/tex]

If A and B are in parallel then their net resistance must be   [tex]\frac{200}{3}[/tex]

[tex]\dfrac{1}{\frac{200}{3}}=\dfrac{1}{100}+\dfrac{1}{R_b}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3}{200}-\dfrac{1}{100}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3-2}{200}\\\\\Rightarrow R_b=200\Omega[/tex]

Answer:

Explanation:

log10 function is required to convert dB into intensity of a sound. Both are measures of loudness of a sound and the relationship can be expressed as follows:

dB = 10 log10(I/Io), where Io is 10^-12 W/m^2

Substituting, 82 = 10 log10(I/10^-12)

I = 0.0001585 W/m^2

or 1.58*10^-4 W/m^2

Answer:

Explanation:

82dB = 10log(Intensity/10^-12)

Intensity = 10^-12*10^(82/10)

=10^(-3.8)

=1.585*10^-4 W/m2

Explanation:

Answer: 0.078

Explanation:

Given variables:

R1 = 25.0 , R2 = 64.0 , I1 = 0.200

Step 1: find V

0.200 = v/25

0.200 * 25 = v

5 = v

Step 2: Solve for I2

I = V/R

I = 5/64

I = 0.078125

Answer:

d. The amount of water vapor in the atmosphere would be lower because it has not evaporated  from the hydrosphere.

Explanation:

Hydrosphere is mass of water found on the water surfaces and above it. While atmosphere is the mass of air surrounding our planet. Hydrosphere includes the water that is found inside the earth's crust, on the surface and also water suspended on the air.

There is interaction between hydrosphere and atmosphere. The water gets evaporated from the hydrosphere and get vaporized to the atmosphere. This affects the humidity of the place.

The humidity tends to be lower in places where the amount of water vapor present in the atmosphere is lower as the water does not get evaporated from hydrosphere.

Answer: The given equation is balanced as  [tex]SO_{2}(g) + O_{2}(g) \rightarrow SO_{3}(g)[/tex]

Explanation:

A chemical equation that contains same number of atoms on both reactant and product side are called balanced chemical equation.

For example, [tex]SO_{2}(g) + O_{2}(g) \rightarrow SO_{3}(g)[/tex]

Here, number of atoms on reactant side are as follows.

Number of atoms on product side are as follows.

To balance this equation, multiply [tex]SO_{2}[/tex] by 2 on reactant side and multiply [tex]SO_{3}[/tex] also by 2 on product side.

Hence, the equation will be rewritten as follows.

[tex]2SO_{2}(g) + O_{2}(g) \rightarrow 2SO_{3}(g)[/tex]

Here, number of atoms on reactant side are as follows.

Number of atoms on product side are as follows.

As there are same number of atoms on both reactant and product side. So, this equation is a balanced equation.

Thus, we can conclude that the given equation is balanced as  [tex]SO_{2}(g) + O_{2}(g) \rightarrow SO_{3}(g)[/tex]

Answer:

Explanation:

The radial velocity method involves watching the spectral lines of a star as a planet orbits the star. Because of the planets gravitational pull on the star, the star will wobble. This causes Doppler shifts in the spectral lines, allowing astronomers to infer the presence of the planets.

Answer:

10,000kgm/s

Explanation:

Since we not told what to look for, we can as well find the momentum of the car.

momentum = mas * velocity

Given

Mass of the car = 2000kg

velocity = 5m/s

Substitute into the formula

Momentum = 2000 * 5

Momentum = 10000kgm/s

Hence the momentum of the car is 10,000kgm/s

The maximum energy is found in visible light from the following areas of the electromagnetic spectrum. Option A is correct.

The electromagnetic spectrum is seen as colors violet, indigo, blue, green, yellow, orange, and red.  Blue light has a very short wavelength, and so produces a higher amount of energy.

Blue light in the visible zone has a very short wavelength. So that it produces a higher amount of energy that's why the blue part of visible light transfers the most energy.

Visible light from the following regions of the electromagnetic spectrum has the highest energy.

Hence, option A is correct.

Answer:

El magnetismo es el conjunto de fenómenos físicos mediados por campos magnéticos. Estos pueden ser generados por las corrientes eléctricas o por los momentos magnéticos de las partículas constituyentes de los materiales. Es parte de un fenómeno más general: el electromagnetismo. También denomina a la rama de la física que estudia dichos fenómenos.

El níquel, hierro, cobalto y sus aleaciones se encuentran entre algunos de los materiales que presentan propiedades magnéticas que son fácilmente observables, y comúnmente se llaman imanes. Estos materiales son ferromagnéticos e interactúan fuertemente con los campos magnéticos externos a la vez que generan un campo magnético propio. Esto permite la tan conocida repulsión y atracción entre los polos de los imanes. Sin embargo, todos los materiales son influidos, de mayor o menor forma, por la presencia de un campo magnético

The question is: You have 500g of ethyl alcohol at a temperature of -40 ° C. How much heat is needed to transform it into steam at a temperature of 150ºC?

Answer: 233700 J heat is needed to transform ethyl alcohol into steam at a temperature of [tex]-40^{o}C[/tex] to [tex]150^{o}C[/tex].

Explanation:

Given: Mass = 500 g

Initial temperature = [tex]-40^{o}C[/tex]

Final temperature = [tex]150^{o}C[/tex]

The standard value of specific heat of ethyl alcohol is [tex]2.46 J/g ^{o}C[/tex].

Formula used to calculate the heat energy is as follows.

[tex]q = m \times C \times (T_{2} - T_{1})[/tex]

where,

q = heat energy

m = mass of substance

C = specific heat

[tex]T_{1}[/tex] = initial temperature

[tex]T_{2}[/tex] = final temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times (T_{2} - T_{1})\\= 500 g \times 2.46 J/g^{o}C \times [150 - (-40)]^{o}C\\= 233700 J[/tex]

Thus, we can conclude that 233700 J heat is needed to transform ethyl alcohol into steam at a temperature of [tex]-40^{o}C[/tex] to [tex]150^{o}C[/tex].

Answer:

1. Solar wind: a stream of plasma.

2. Coronal mass ejection: includes prominences and solar flares.

3. Gamma ray photon: energy released during nuclear fusion.

Explanation:

1. Solar wind: a stream of plasma i.e charged particles such as ions, protons, alpha, and electrons that continuously escape at high speed from the Sun because of the very hot plasma contained in the solar corona.

2. Coronal mass ejection: includes prominences and solar flares that flow outward into interplanetary space. Thus, it's a release of solar wind plasma and magnetic field from the outer atmosphere or corona of the sun.

Additionally, a solar prominence is also known as filament and it can be defined as a large, bright, dense cloud of luminous ionized gas such as hydrogen, sodium calcium, etc., that erupts (extends) from the surface of the sun. It can linger in the corona for a very long time, reaching hundreds of thousands of kilometers into the sun's atmosphere (space).

3. Gamma ray photon: energy released during nuclear fusion of radioactive isotopes such as cobalt-60 or cesium-137. It has the shortest wavelength and highest energy in the electromagnetic radiation spectrum.

An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.

Answer:

La presión que los patinadores ejercen sobre el hielo es 7,848,000 Pa

Explanation:

Los parámetros dados de los patinadores en la pala son;

La longitud de la hoja en el patín, l = 30 cm = 0.03 m

El espesor de la hoja, t = 5 mm = 0,005 m

El peso de las dos personas, m = 120 kg

Suponiendo que la sección transversal de la cuchilla sobre el hielo es rectangular, tenemos;

A = l × t

∴ A = 0,03 m × 0,005 m = 0,00015 m²

La fuerza de peso de los dos patinadores, W = m × g

Dónde;

g = La aceleración debida a la gravedad ≈ 9,81 m / s²

m = La masa de los dos patinadores = 120 kg

∴ W = 120 kg × 9,81 m / s² = 1,177,2 N

Presión, P = Fuerza, F/(Área, A)

∴ P = (1.177,2 N) / (0.00015 m²)= 7,848,000 Pascals

La presión que los patinadores ejercen sobre el hielo., P = 7,848,000 Pascals
